Title: Improvements in gaseous electric conduction devices
IPC: H01J61/26
Filed: 1925-07-02
Abstract: 237,235. British Thomson-Houston Co., Ltd., (Assignees of Charlton, E. E.). July 17, 1924, '[Convention date]. Vacuum tubes.-Discharge devices operating by the ionization of a gaseous filling contain the oxide of an alkali metal, such as caesium or rubidium, and preferably also a small quantity of an alkaline-earth or other oxidizable metal, the operating voltage being thus reduced by absorption of deleterious gases. After the bulb has been heated to 450 C. to remove v a p o u r and evacuated, caesium is introduced, for example, by heating a mixture of caesium chloride and a reducing agent such as calcium in a chamber connected to the bulb, and is oxidized by admitting oxygen and heating to 50 C. The excess oxygen is removed and magnesium, calcium or other alkaline earth metal is deposited on the bulb by affixing to an electrode and introducing the device into a high-frequency electromagnetic field, the bulb being finally filled with helium or neon at 5 to 80, and preferably 19, m.m. of mercury. In a modification, a mixture of caesium chloride or other alkali halide with an excess of alkaline-earth metal is introduced, for example, as a pellet. On continued heating, both metals are deposited on the bulb and the alkali metal is then oxidized as before, the alkaline-earth metal being unaffected if the temperature is not raised above 50 C. Either method may be applied to the rectifier described in Specification 237,236, and comprising two tungsten wires which are in hard glass tubes and the exposed ends of which form anodes surrounded by interconnected housings forming the cathode; in the first method, the alkaline-earth metal is fixed to the cathode before, vaporization. Either method may be applied to a lamp containing plate electrodes 17, 18 of iron, nickel, molybdenum or aluminium, separated by a sheet 24 of hard glass, fused quartz or other refractory dielectric, one lead 19 being insulated from the plate 18 by mica 25 and connected to the plate 17 by a screw 22; in the second method, a pellet 28 of the reaction mixture is heated by a tungsten spiral between the leads 19, 20 and the spiral 28 is ultimately burned out. The alkali metal may also be introduced into a lamp as a vapour and subsequently oxidized. Reference has been directed by the Comptroller to Specifications 175,254, and 224,544* (as open to inspection under Sect. 91 of the Act).

Patent GB-1044298-A (GB)
Title: Characters recognition techniques
IPC: G06V10/26
Filed: 1963-05-02
Abstract: 1,044,298. Automatic character reading. THOMPSON RAMO WOOLDRIDGE Inc. May 2, 1963 [May 2, 1962], No. 17425/63. Heading G4R. In character recognition apparatus the scanning means makes a series of vertical strokes moving across the paper, the strokes being close together until the character is cut and then more widely spaced as shown in Fig. 1. The characters are scanned by a cathode-ray tube 10, Fig. 2 (not shown), giving a flying spot, transmitted light being received in a photo-multiplier 16. Sehmitt trigger 38 sets and resets for " black " and " white " signals. The vertical control plates are controlled by a sweep voltage from generator 24 which selects successive lines of text. Generators 28 and 30 produce the high and low-speed scanning voltages, the latter being driven through a counter 42 from the former. Fast and slow transmission gates 34, 46 are opened alternatively by " character present " flip-flop 40, which is set when a " black " signal appears at the output of trigger 38 indicating that a character has been out and is reset either by the detection of a blank scan showing that the scanning of the character is complete, or by a counter 50 which counts five slow scans and then causes the scanner to revert to highspeed scanning. Recognition.-Fig. 4a (not shown) illustrates signals emerging from the Schmitt trigger representing character " L." These square pulses are differentiated at 72, Fig. 3 (not shown), giving signals of Fig. 4b (not shown), and applied to multivibrator 74 which gives positive and negative pulses for the leading and trailing ends of the original " black " pulses, Fig. 4c (not shown). This signal passes to delay line 68 designed to contain the signals for the whole character. In each character tappings are provided at the points corresponding to the positive and negative pulses and adding resistors apply the summed positive and negative signals to either side of a differential amplifier. An output is obtained if the correct pattern of signals for the corresponding character is present. To prevent the first part of a character (e.g. the vertical stroke of " L") giving a false recognition signal indicating another character (e.g. " 1 ") the outputs of networks corresponding to characters which could become confused in this way are gated together so that, for example a " 1 " output is given only if there is subsequently no output on the " L " or " U " leads. Necessary delays bring the signals into time coincidence.

Filed: 1938-06-14
Abstract: 510,752. Automatic and semi-automatic exchange systems. GENERAL ELECTRIC CO., Ltd., SHELLEY, G. H. L., and CARPENTER, O. I. June 14, 1938, No.17591. (Class 40 (iv)] In a private automatic exchange having a manual board for the completion of incoming and outgoing calls, the local feed bridge is automatically cut out on such calls. The exchange may, for example, be one for the use of the personnel of a ship and is temporarily connected to a main exchange on shore, and it may be combined with a manual exchange for the use of the passengers. The arrangement described employs finder - connector links, only the connector portion being shown, and the manual board is reached over the tenth level of the connectors. The main exchange junction is plugended. Incoming call. On plugging into jack JA or JB, sleeve relay SA completes the loop to the line circuit associated with the jacks JA, JB, whereupon the call is extended over a callfinder (not shown) to a connector. The latter is set in the usual manner under the control of the operator's dial IS which is connected up over key DK. Test relay H operates during the relapse of E provided the wanted line is idle, and ringing current is applied over relay F which energizes upon reply. Since SA is up, a circuit is now made for switching relays K, KA, which lock under the control of SA. only, complete a through metallic circuit to the main exchange and take over the control of release. A. supervisory relay is included in one wire of the junction. Outgoing call. When the subscriber dials O, relay D operates over the vertical wiper VB on the tenth level and closes a circuit over post springs NP for the rotary magnet R, with which it interacts until an idle outlet is reached. On the relapse of E, relay K switches through to the line circuit associated with the jacks JA, JB. Relays LA, BA. energize, lighting the calling lamp CA and sending a tone signal to the subscriber, and switching relay KA operates. The operator inserts a normal answering plug in one of jacks JA, JB, and on learning that a main exchange call is required, inserts the junction plug in the other jack and obtains the wanted call. Sleeve relay SA holds K, KA during conversation.

Patent GB-1543882-A (GB)
Title: Overload protection of electrical apparatus
IPC: H02H6/00
Filed: 1977-04-28
Abstract: The device contains a temperature sensor (6), which is arranged in the upper layer of a dielectric fluid, a correction device and a changeover circuit (9). The latter contains threshold-value elements (10, 11, 12, 13) for a small overload, a threshold-value element (14) for a large overload, and a load-disconnection circuit (17). The correction device contains a load-current sensor (7) and a function- forming device (8). The function-forming device (8) emits a signal which corresponds to the excess temperature of the winding of the apparatus above the temperature of the dielectric fluid and, together with the output signal of the temperature sensor (6), is applied to the threshold-value elements (10,11.12,13;14) of the changeover circuit (9). The load-disconnection circuit (17) is electrically connected to the threshold-value elements (10,11,12;13) for a small overload, for selective emission of the output-control signals. Such a device for overload protection of electrical induction apparatuses allows the change in the winding temperature which is caused by the load currents and the change in the temperature of the dielectric fluid as a result of the influence of various types of external influences to be detected in a complex manner, in order to overcome the possibility of failures of the apparatuses. <IMAGE>
